Definitions
- the invention relates to an exhaust gas turbine for a turbocharger, the one of a has double-walled casing encased turbine wheel.
- Turbocharger used in the so-called supercharging of an internal combustion engine.
- part of the exhaust gas energy lost per se becomes the drive an exhaust gas turbine, which is connected via a shaft with a supercharger (Air compressor) is coupled for the intake air.
- This expresses the condensed Air in the cylinders of the internal combustion engine, creating more mass for the Combustion is available.
- Cast housing with its high mass withdraw the exhaust gas, especially in the heating phase, a lot of heat.
- the heating phase during the toxic exhaust gas components released into the atmosphere is therefore relatively long.
- a catalytic converter only starts to oxidize much later from e.g. Carbon monoxide can begin. This is particularly the case disadvantageous from an ecological point of view.
- Latest emissions regulations the one Prescribe measurement of exhaust gas emissions from internal combustion engines during cold starts, cannot be fulfilled in this way.
- the state of the art also includes exhaust gas turbines in sheet metal construction (DE 100 22 052 A1).
- Sheet metal constructions have so far not been used in the passenger car sector. You point namely the disadvantage of lower burst safety in the operating situations in which the turbine impellers are loaded with excessive speeds and be destroyed by it.
- the exhaust side Turbine housing can be run in two channels. That is, the exhaust gas flows of two cylinders of an internal combustion engine are up to led to the turbine impeller separately. This is a significant increase in Dynamic response and an additional increase in performance or an optimized overall system efficiency compared to one connected system.
- the object of the invention is based on the prior art based, an effectively improved exhaust gas turbine in a double flow design to create that is burstproof, requires little mass, ensures increased dynamics and improved responsiveness ensures.
- the divider provided in the inner jacket divides it into two chambers, which guarantees the double-flow version and especially 4-cylinder internal combustion engines served to advantage. It is also advantageous that through the overlap of the approximately parallel to the axis of rotation of the turbine impeller extending radially outer axial leg of the outer casing, namely under Formation of an approximately V-shaped gap, a significantly improved burst safety is achieved. In this context it is important that the Do not touch both axial legs over their entire length, but that only the face of the overlapping axial leg on the outer surface of the engaging axial leg is fixed by welding.
- the kinetic energy of these particles can initially be in deformation energy of the engaging axial leg and, if the engaging Axial leg then comes into contact with the overlapping axial leg, then also on the overlapping axial leg in deformation energy being transformed.
- the sheet metal construction also makes a considerable difference Reduced mass use compared to a cast construction achieved. Herewith is associated with increased dynamics of the vehicle drive, which also improved response behavior of the entire drive system becomes.
- the outer shells can be formed in one layer.
- the inner shells of the inner casing can be used with the Separator must be joined by welding.
- the radially outer area of the separator is approximately is angled like a leg parallel to the axis of rotation of the turbine impeller.
- the radially outer edge areas of the inner shells are then inside and placed on the outside of this short leg and on the circumferential side with a fillet weld of the inner edge area and the short face Leg of the separator and the outer edge area the inner shells welded to the separator.
- Integrate means converting deformation energy can e.g. be formed by knitted wire or additional sheet metal inserts, which in the gap will be embedded.
- connection of the outer casing with the bearing housing for the turbine impeller can be done with the features of claim 6. This will the radially inner edge region of a transverse to the axis of rotation of the turbine impeller extending radial leg of an outer shell on one circumferential shoulder of a flange socket welded using fillet weld.
- the flange is in turn connected to the bearing housing for the turbine impeller. The paragraph is located approximately in the middle section of the Flange connection.
- the inner casing on the bearing housing is also defined in accordance with the patent claim 7 about this flange.
- the radially inner one Edge area of the inner shell of the bearing housing The inner jacket is attached to the face of the flange connector and welded to it.
- the thickness of the inner shells is smaller than the thickness of the Dimensioned outer shells.
- the inner shells of the inner jacket run very thin-walled, which makes them very quick to operate heat.
- the light-off behavior of a catalytic converter becomes significant accelerated.
- the invention enables that for the inner jacket and the Outer sheath differently tailored to their respective function Materials can be used.
- the inner jacket is preferred made of a heat-resistant material. This can be done with thin-walled sheets be used. This has an advantageous cost effect.
- the outer jacket can consist of inexpensive materials, since here the temperature load due to the insulating effect of the air gap between the inner jacket and the outer jacket is considerably lower.
- 1 is a bearing housing for one Exhaust gas turbine 2 denotes the bearing of the shaft 3 of a turbine impeller 4 serves.
- the turbine impeller 4 is enveloped by a double-walled casing 5, which is composed of an inner jacket 6 and an outer jacket 7.
